Verdict: Great controls, but the microphone hums.

Logitech's headset seems to be aimed more at VoIP nattering than games and music, but it still has plenty going for it no matter what your chosen pastime is. It connects by USB, so there's a single connection for the headphones and microphone, dispensing with the need to scrabble around the back of your PC. It also means that you can't use this headset with anything except PCs and Macs.

The controls are built into the right headphone and work brilliantly. The top edge is a volume up button, the bottom edge lowers the volume and the centre mutes the microphone. A switch on the back accesses three EQ presets optimised for telephony, games and music. This is much easier to use than an in-line remote, and means that you don't need to take your eyes off the screen to adjust the settings. Muting the microphone activates a red LED in the microphone, so there won't be any confusion as to whether or not you're being heard.

The microphone has a smaller quoted frequency range than those of the other headsets, ranging from 100Hz to a relatively low 10KHz. However, this is plenty for capturing speech, and the microphone was the brightest and clearest of all those on test, although the thin, transistor radio-like quality wasn't flattering. The microphone also emitted a humming noise; while it wasn't enough to interfere with intelligibility, it was audible in normal use.

The headphones exhibited a similar sound quality to that of the Sennheiser PC 131 - clear and detailed, though not overflowing with deep bass and lacking the vibrancy of the more expensive models. The maximum volume isn't very high either. It's more than enough for pop music, which tends to be mixed at a loud volume, but classical music, games and DVD soundtracks won't make your ears bleed any time soon - although this is possibly a good thing. Ultimately, for £23, we're more than happy with the sound quality, which did justice to all our audio sources when auditioned in isolation.

Logitech's microphone is a little disappointing, but the headphones are great and the USB interface is worthwhile if your PC only has integrated sound.
